A-D

A

Abseil—(pronounced AB-sail) To make a controlled descent on a fixed rope. The term is typically used in Europe and Australia. See rappel.

Accessory cord—Nylon, Kevlar® or Spectra® cord sold in a range of diameters, typically smaller than those of climbing ropes. Used for a variety of things including slings, anchors, prusiks, and emergency tie-offs. Accessory cord is static, or very low stretch.

ACD (Active Camming Device)—Protection device that secures in rock cracks or pockets by means of spring-loaded cams. See SLCD.

Active protection—Any piece of climbing protection that has moving parts, typically with springs. Examples include spring-loaded camming devices, sliding wedges and tube chocks.

Aid climbing—A type of climbing that makes use of rope, fixed bolts, pitons or foot slings, rather than features on the rock itself, to ascend the face. Opposite of free climbing.

Anchor—A point of attachment for a climbing rope, usually made with slings, runners or the rope itself. May be top-rope anchors, belay anchors or a protection piece mid-climb.

ANSI (American National Standards Institute)—Establishes and enforces industrial standards in the United States. See CEN.

Approach—The route or walk in to the base of a climb.

ASTM (American Standards for Testing and Materials)—Establishes materials specifications and testing standards in the United States.

Auto-lock—Spring-loaded, twisting mechanism on a carabiner gate that locks by itself when the gate is closed.

 

B

Backup—Any additional protection that is added to provide redundancy to an anchor.

Bashies—Malleable anchors that are literally bashed into small cracks for use in aid climbing. Tough to remove.

Belay—To keep a climber from falling too far by using friction on the rope. The system that stops a climber’s fall. It includes the rope, anchors, belay device and the belayer.

Belayer—The person who manages the rope so as to catch the climber on the other end in case of a fall or a slip.

Bent-gate carabiner—Sport-climbing carabiner used on the rope-clipping end of a quickdraw. The bent gate provides a larger opening than straight-gate carabiners provide for clipping in the rope.

Board-lasted—Shoe construction in which the upper is attached to a stiff insole (also called the board). In board lasting the insole is fixed to the last/form, then the upper of the shoe is wrapped around this assembly. In the final step the midsole, rands and finally the outsole are attached to the shoe.

Body belay—Belay technique using friction of the rope passing around the belayer’s body to slow and hold a fall. It is often painful for the belayer and not effective in every situation, but can be used in emergency situations if no belay device is available.

Bolts—Metal expansion bolts drilled into the rock for use as protection on sport or aid climbs. Hangers are attached to the bolts for clipping in your rope.

Bombproof—A hold or anchor that is thought to offer the utmost security; for example, a top-rope anchor around a large, stable tree trunk or immovable boulder.

Bottleneck—A crack with converging sides. Good for placing tapers or other passive protection.

Bouldering—Climbing close to the ground without the use of a rope. Typically used for practicing traverses, weight transfers, and foot and hand placements. Can be done on boulders or at the base of a rock face.

Runner—Loop of nylon webbing used to attach the climbing rope to protection or to make anchors. Can be tied (homemade) or sewn (bar-tacked commercially).

Runout—The distance between a climber and his or her last piece of protection. A long runout equates to a long fall. In alpine climbing, it’s the area below a climbing route onto which a climber would land if he or she were to fall. Look for a safe runout on a snow slope before glissading.

S

Screamer—A long fall on a rope, frequently with screaming. Also the model name of an energy-absorbing runner made by Yates.

SLCD (Spring-loaded camming device)—A piece of active climbing protection composed of a number of cams on a stem with a trigger bar. When the bar is pulled back, the cams compress to a size small enough to fit inside a crack or pocket. When the bar is released, the cams flare outward and rotate/wedge into place, providing protection. The rope is then clipped with a runner to this piece of protection. See Friend, Camalot, TCU.

Slingshot rand—Internationally patented by La Sportiva, this one-piece rubber rand wraps around the entire foot, preventing stretch and driving the foot forward for a powerful forefoot fit.

Slip-lasted—The method of footwear construction in which the upper is sewn into a sock and then slipped onto the last. Slip-lasted shoes normally do not have an insole and get their “stiffness” from the midsole, which is located just above the outsole. Slip-lasted rock climbing shoes tend to be sensitive and less stiff than board-lasted shoes.

Slipper—A snug-fitting sport climbing shoe that is slipped on rather than laced. Popular for gym climbing and bouldering.

Smear—Climbing technique in which the sole of the shoe, plus proper weight over the feet, provides traction for moving upward.

Snaplink—Name for carabiner, popular in the military.

Solo—To climb alone without protection.

Speed climbing—A competition that tests how far a climber can progress in a given time or how long it takes to complete a given climb.

Sport climbing—Rock climbing using pre-placed protection such as bolts or a top rope. Frequently involves difficult, gymnastic moves. Opposite of traditional climbing.

SRENE—Acronym for Solid, Redundant, Equalized and No Extension, which refers to the qualities of a good climbing anchor.

Static—Limited movement or stretch, when referring to a climbing rope. Static ropes are used for rescue, caving and rappelling, but do not stretch enough to absorb the impact of a leader fall when climbing. Opposite of dynamic.

Stemming—Technique in which the hands and/or feet are pressed in opposition far out to each side, as in a dihedral or wide chimney.

Sticht plate—Original friction device for belaying developed by Franz Sticht. Consists of a plate with 2 holes and sometimes a spring on the bottom. A bight of rope is passed through one of the holes and locked to the belayer’s harness. The plate provides friction on the rope to slow or stop it. The spring keeps the rope from getting wedged in the plate’s holes. (Both holes are used only when twin/double ropes are being used.)

Stopper—See taper, nut or chock.

Swami—Traditional climbing harness made by wrapping webbing around the waist. Also refers to the waist-belt portion of a climbing harness, sometimes sold separately from the leg loops for a custom fit.

Toe displacement—The degree to which a climbing shoe curves the foot toward the inside edge, determined by the shoe’s sole shape.

Top rope—A rope that is passed through a fixed anchor at the top of a climbing wall or cliff, with each end tied to the climber and the belayer at the bottom. A top rope (with a watchful belayer) ensures that the climber is always protected from falling very far, and is thus a good way to learn to climb. “Top-roping” is the term for this type of climbing.

Traditional or “trad”—Rock climbing using protection placed by the lead climber and removed by the second, as opposed to sport climbing, in which protection (bolts) is pre-placed. See sport climbing.

Triple runner—A 14-foot length of webbing tied into a loop with a water knot, used for attaching pro to the climbing rope, but more often for creating anchors. Usually must be wrapped three times to be carried over one shoulder of the climber.

Tube chock—Cylindrical, spring-loaded protection. Made of telescoping aluminum tubes that expand and wedge in place. Typically used in very wide, vertical cracks and in holes where other protection will not fit.

Twin rope—Climbing rope designed to be used in pairs with both strands running parallel through the same protection. Thinner in diameter than single rope. See half rope and single rope.

U
